World of Warcraft Easter Egg - Land of the Lost Reference in Ungor'o Crater

Go to the Alliance camp in the North of the crater. Go to the mouth of the cave and you will see two characters, a human male and female. Their names are Willeden and Hol'anyee Marshal, I think.
This is a reference to a TV show that aired several years ago, starring a family lost in treacherous jungles in the past. They were Holly, Will, and Marshal. The whole zone is one big joke, so I hope someone will point out some other jokes.
